Description
Technical field
The utility model belongs to the auxiliary device of thermal power plant Air-cooled Unit, relates to a kind of Air-cooled Unit condensing plant heat energy utilization device.
Background technology
When the rich coal water-deficient area of China is built the power station, must build up the air cooling power station according to national water-saving policy, because the air temperature characteristics makes the condensing plant operation of Air-cooled Unit that certain degree of difficulty be arranged, the northern China air quality is poor in the winter time, easily cause certain dirt on the surface of the condensing plant of Air-cooled Unit, cause the heat transfer property of the condensing plant of Air-cooled Unit to reduce, so must carry out antifreeze to the condensing plant of Air-cooled Unit; But during the broiling summer, environment temperature is up to more than 30 ℃, make that the condensing plant cooling capacity of Air-cooled Unit is not enough again, unit is aestivated difficult, cause the power consumption of air cooling island blower fan to increase, the way that solves is to increase by a cover spray equipment at present, and air themperature is reduced, guarantee the back pressure of Air-cooled Unit, but will consume certain demineralized water and water pump power consumption.
Existing air cooling power station steam turbine, the air cooling system back pressure is generally 0.015-0.04KPa, about 54～75.8 ℃ of exhaust temperature, and this part heat generally is to come cooling steam by the air cooling island of power plant blower fan with air, hot-air directly is discharged in the atmosphere, do like this and both caused energy huge waste, again environment is caused serious thermal pollution.
Summary of the invention
The purpose of this utility model provides a kind of Air-cooled Unit condensing plant heat energy utilization device, to improve the heat energy utilization rate.
The utility model is achieved through the following technical solutions:
Air-cooled Unit condensing plant heat energy utilization device, comprise shell, be connected the condensate water collector of outer casing bottom, the cooling intake chamber that is connected with side wall of outer shell, cooling water-supplying chamber, hydroecium header, be arranged on admission guide tank, baffle plate, the plate type heat exchanger of enclosure, wherein said cover top portion offers exhaust steam inlet, sidewall offers the incondensable gas outlet; Described cooling intake chamber is provided with water inlet, and cooling water-supplying chamber is provided with delivery port, is provided with cooling water turnover chamber baffle plate between cooling intake chamber and the cooling water-supplying chamber; Plate type heat exchanger is connected with cooling water-supplying chamber with the cooling intake chamber respectively with the hydroecium back tube sheet by the hydroecium front tube sheet, described plate type heat exchanger leaves certain clearance by several vertically arranged plate Shu Zucheng that is combined by two plates between plate bundle and the plate bundle; Described condensate water collector bottom offers the condensate water outlet.During work, cooling water enters in the plate bundle that is connected with the hydroecium front tube sheet by the cooling intake chamber, enters the hydroecium header through the hydroecium back tube sheet then, has finished a flow process; Stay from the other plate beam passage of opposite direction again and get back to cooling water-supplying chamber, finished another flow process; Passage between two plate bundles is as the passage of steam, the passage of a plurality of steam that steam is formed by plate type heat exchanger, and condensed liquid enters the condensate water collector, discharges from the condensate water outlet then; Baffle plate and plate type heat exchanger have formed countercurrent zone, and incondensable gas is taken away by the incondensable gas outlet.
Described plate type heat exchanger is a corrosion resistant plate bundle structure.
The utility model utilizes the high characteristics of air cooling system back pressure, overcome steam discharge that existing Air-cooled Unit the produces deficiencies such as when summer, increasing by a cover spray equipment again that is not used, the Air-cooled Unit heat energy utilization device of a kind of and existing Air-cooled Unit condensing plant system parallel running is provided.
Compared with prior art, the utlity model has following advantage:
(1), reduce the thermic load of existing Air-cooled Unit condensing plant because the heat of steam discharge reduces, the load of air cooling island blower fan also reduces thereupon, can save the part station service;
(2) adopt the utility model after, about the general 50-78 of the water after the heating ℃, can be used for heating in the winter time, also can be used as the power station in summer and produce and use chemical water, perhaps as the hot water of the daily usefulness of having a bath and live.
The utility model has solved the difficult problem of the heat energy utilization of Air-cooled Unit condensing plant on the one hand, compares with conventional power plant, has reduced the needed operating cost of Air-cooled Unit condensing plant condensation; Broken through the mindset that conventional power plant utilizes steam turbine to draw gas to heat heating water on the other hand, improve heat-economy, saved the energy and had good energy-saving effect, reduced thermal pollution at the same time, also improve worker's living condition, played the effect of energy-saving and emission-reduction; Both satisfy the heating temperature requirement, saved water again greatly, met energy-saving and emission-reduction, the water-saving policy requirement of country.
